Limit CPU question

I have typed every account to use 20% of the cpu but when one account hits the 20% CPU usage the server hits the full cpu usage (4 cores).
Now the question: why is the the option to limit the cpu when it dosent work?

Definitely it should not work like that, suppose that is misconfigured somehow. Can you please provide more examples including 'lvectl list' , lveps and top header output?
